(Frodo) Use util-linux macro's when printing help or version numbers
A new file util-linux-compat.h has been introduced; it more or less contains
what c.h contains in util-linux.
This implements the following util-linux git commits:

(Frodo) Merge from util-linux
Two changes related to coverity scan. Note that these were not actual bugs,
but as they make the code a little clearer perhaps, I have committed them
anyway.
